aes_encrypt

Description

Uses the AES_128_ECB algorithm to encrypt a string and returns a binary string.

AES is short for advanced encryption standard and ECB is short for electronic code book. The key used to encrypt the string is a 128-bit string.

Syntax

aes_encrypt(str,key_str);

Parameters

str: the string to encrypt. It must be of the VARCHAR type.

key_str: the key used to encrypt str. It must be of the VARCHAR type.

Return value

Returns a value of the VARCHAR type. If the input is NULL, NULL is returned.

Examples

Use this function to AES encrypt starrocks and convert the encrypted string into a Base64-encoded string.

mysql> select to_base64(AES_ENCRYPT('starrocks','F3229A0B371ED2D9441B830D21A390C3'));
